    'Save Medadata to file' - but only some?

    Roy Kaye Community Member

      Hello, I read an Adobe Lightroom discussion from November 2011. I am looking to start using Lightroom (have been using capture nx2) but need something answered please:

       

      It stated that 'Save Medadata to File' will copy most but not all of the metadata changes that you have made within Lightroom', which got my attention, and seemed a bit worrying.

       

      It suggested that this problem was for both proprietary raw formats with xmp sidecar files, and dng files (also TIFF etc I think). I also understand, or think I do, that it's only a problem

      when you export from Lightroom to another editing program (or photoshop at least). I also read something similar on a recent post here, but I didn't find it very clear.

       

      The problem is that some things are not included in the metadata write command....the develop history, stacks, collection membership, flags, virtual copies.

       

      All of these things, apart from maybe flags, I need, and can't imagine that I can't use these important options, so I really must be missing something. And surely I would need to  save the

      metadata to file to send images to NIK software etc for further editing. I read it that if you stay in Lightroom there is no problem, as I think the catalogue has all the metadada, but that

      won't happen, or not all the time.

       

      I don't understand this, and can't quite believe it, so would be most grateful for advice, thanks

          These items are never written to XMP. Period.

           

          The purpose of XMP is to communicate with other applications, but the things you mention ... develop history, stacks, collection membership, etc. are Lightroom constructs, they only make sense within Lightroom and are meaningless to other programs, they cannot make use of it. So, these items are not written.

           

          Perhaps you could explain why you want these items written, what you (or another program) might do with them, so we could figure out an alternative.

            Thanks for your reply, which is much appreciated

             

            The truthful answer is that I don't know why I want these items written. It's just that what I read seemed to make a negative out of it, but

            I don't know why. Perhaps you might be able to clarify why this might be a problem, if that's what it is - I mean in what circumatance(s)

            might this be a problem?

             

            I just presumed that it might prevent me, within Lightroom to use these features - or did they mean that they would just not be available

            to someone I might send the files to, or whatever?

             

            I will just need to edit files in Lightroom (I will be changing my NEFs to DNGs, editing in Lightroom, using NIK software/maybe other

            software too, and sending photos to a website such as Zenfolio, and also to a printer or whatever)

             

            I suppose you could say that the post I read alluded to a problem, but didn't explain (or I didn't understand) what the effects would be, at

            least as far as I am concerned). I mean they didn't say 'this is, or could be, a problem because.....'

             

            Thanks

              As far as I know, there are no situations where this is a problem. I would imagine for 99.9% of Lightroom users, this isn't a concern at all.

               

              As I said, things like collections and virtual copies (and the rest of that list) are meaningful only inside of Lightroom. There is no reason to transmit this information to other people, or other applications.

                These items exist only in the Lightroom Catalog.  You have the option of writing the develop settings to xmp sidecars or directly into DNG files, so that other programs can read them.  Another advantage of writing develop information to photo files is that your settings will be backed up in the photo files so if the Lightroom Catalog is lost, you still have all of your develop settings which can be imported into a new catalog.  Of course it is best to have all the information in the Catalog available which can be assured by keeping multiple backups of the Catalog.  Also, if you expect to have your photos and Lightroom Catalogs in the future, a good backup scheme is essential with at least two copies of all of your photos and Catalog backups, and one off-site back up.  It is also a good idea to have a backup scheme that avoids transferring corrupted or accidently deleted files to the backup.

                  Many thanks, I think I understand now that the develop history, stacks, collections etc are always

                  available within Lightroom, but not to other programs, and that this should not be a problem. I am not

                  sure if, for example, a photo edited in Lightroom, then sent to say NIK for further editing before being

                  brought back to Lightroom, could then be put in a collection, but don't see any problem

                   

                  Thanks again for clarifying
